To all 'whom it may concern:

Be it known that l, FREDERICKH. UM-

HoL'rz, a citizen of the United States, re

the provision of an apparatus oflthis character wherein water from a well, stream or the like can be trapped so that the same will be raised for its discharge under the action of compressed air; the water when being raised is designed to automatically -control l the compressed airsupply to the water containers forming the traps therefor to assure v a 4'continuous discharge of water from the said apparatus when its delivery faucet is open.

Another object of the invention is the provision of an apparatus of this character wherein a novel form of water actuated motor is employed to automatically control the Vsupply of compressed air used for raising the water whereby it may be discharged or delivered from the apparatus.

A still further-object of the invention is the provision of an apparatus of this character wherein its construction is of novel form to effect the perfect and accurate working thereof.

A still'further object of the invention is the provision of an apparatus of this character which is simple in construction, re-

liable and' efficient in .0peration, strong, durable, possessing a minimum number of parts, and also which is inexpenslve in manufacture.

Referring to the drawings' in idetaihfA designates a water well and B the platform,

which has a removable section C closingthe upper end of the well asl usual, whileinstalled for use in raising water from the well is the apparatus hereinafter fully described. 1

The apparatus comprisesa pair of spaced parallel vertical water containers or receptacles 10 and 11, respectively, forming traps which are suitably supported within the well .A in proximity to its bottom, each trap being formed with an inlet opening 12 in its bottom, and this opening is closed through the medium of an inwardly swinging flap valve 13 of any approved type, so that on the entrance of water-into the trap the valve will become closed to prevent the discharge'of water through the opening 12 in itsbottom. In order to produce a continuous flow of water' from Ithe apparatus the two traps 10 and ,11 are employed, andv any number of the same may be used, these' traps being submerged in the water supply as usual. For emptying the receptacles or traps 10 and 11, each is provided at its lower end with a short outlet pipe connection 14, these connections being cast integrally and connected to the lower end of a single pipe 15 which extends upwardly vthrough the well A and leads-to a suitable point of delivery. Each pipe connection 14 is provided with a check valve 16 to pre- 'venteback flow of water into its respective lreceptacle or trap, and the upper or delivery end of said pipe 15 is provided with a' valve 17 to control the delivery or discharge of water therefrom. y

The openings 12 in the bottoms of the receptacles or traps 10 and 11 are large enough when not under air pressure.

Arranged exteriorly of the well A and supported upon the platform B is a reservoir or tank 18 for receiving compressed air from any suitable source, in this instance the compressed air being supplied from any approved form of pump 19 which is suitably connected with the tank.

For controlling the supply of air admitted to the receptacles or traps 10 and 11, therel is arranged in the delivery pipe 15 a lobe motoror gear motor which comprises a casing 20 having arranged therein the lobe or gear wheels 21 which are in mesh with each other and are fixed to shafts 22 journaled in the casing 20, one of the shafts being extended without the same and is provided with a gear pinion 23 which in turn meshes with a larger gear wheel 24 onthe stem 25 of a revolving valve 26 which is mounted' in a suitable casing 27. For convenienceof construction, the motor casing 20 and the valve casing 27 may be cast integrally, as shown.

Leading from the tank or reservoir 18 is an air supply pipe 28 having branches 29 leading through the valve casing 27 to the receptacles or traps 10 and 11, respectively.

The valve 26 within the casing 27 is ported to allow admission of air to one receptacle or trap while the' other is exhausting. In Fig. 6 of the drawings the valve is shown in full lines with one port in position to admit air through one branch 29 to the receptacle or trap 10, and by dotted lines the other port in the said valve is in position to allow the exhaust of air through the other branch 29 from the receptacle 11, the outlet or discharge ports 30 being provided for Athis purpose to exhaust the ycompressed air to the atmosphere alternately 'on the working of the valve 26 in its casing 27 when the apparatus is in operation.

1t will be noted in this instance that there are two admissions and two exhausts of air from each of the receptacles 10 and 11v forming the trap for the water during each revolution of the valve 26, but the arrangement of the parts in said valve to allow any other number of ad-missions or exhausts may be left to the discretion 'of the designing engineer of the apparatus.

When no water is allowed to deliver through the pipe 15 the parts of the motor and valve are passive, but by opening the valve 17 in the delivery pipe 15 the flow of water through the motor revolves the valve 26, allowing the air from the tank or reservoir 18 to empty the receptacles or traps 10 and 11 alternately.,

By arranging proper lap of the parts in the valve 26 and admitting air to one ceptacles or traps 10 and 11 may be completely filled with water before air is admitted thereto from the said reservoir or tank and before all of the water is forced from either of the chambers. When the 4 parts have been arranged and adjusted no air will be allowed to pass up the deliveryl pipe 17 throughthe motor.

Arranged within the pipe 28 is a pressure relief valve 31 which may be used in the said pipe to limit the air pressure supplied to the receptacles or traps.

It will be apparent that the water when raised will operate the motor which directly controls the valve for the admission and exhaust alternately of air to and from'the receptacles or traps 10 and 11, the air being supplied from the reservoir or tank hereinbefore described.

From the foregoing description, taken in connection withv the accompanying drawings,`the construction 'and manner of operation of the device will'be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is An apparatus of the character described comprising a pair of water containers adapt ed to be lowered within a water well spaced from its bottom and having valved inlets, a compressed air tank adapted to be located exteriorly of the well, a water discharge pipe common to said containers, a gear caslng arranged in said discharge pipe, gear wheels journaled in the casing and meshing with each other, a valve casing connected with the gear casing and having dual communication with the compressed air tank, the said valve casing having a pair of exhaust Ports, branch air supply pipes leading from the valve casing to the container, and a valve within the casing having driven connections with one of the gears lin the gear casing1 and adapted to alternately allow admission of air to one receptacle and the exhausting of air from the other receptacle.,
